Seroepidemiologic survey of hepatitis G virus in selected population of Shanxi, Qinghai and Xinjiang Provinces (region) of China / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the serological features of hepatitis G virus (HGV or GBV) in selected population of Shaanxi, Qinghai and Xinjiang Provinces (region).</p><p><b>METHODS</b>Enzyme-linked immunosorbent assay (ELISA) was used to determine IgG antibody against GBV (anti-GBV IgG) in serum specimens of 1469 individuals from the 3 provinces (region).</p><p><b>RESULTS</b>The positivity rate of serum GBV-IgG antibody in ethnic minorities (4.11% in Tibetan, 5.36% in Mongolian, 4.55% in Uigur, 4.00% in Hui population) was slightly higher than that in Han population (1.36%-1.73%), but the differences were not significant (P>0.05). The positivity rate of serum GBV-IgG antibody in drug abusers (11.30%, 34/301) was remarkably higher than that of the normal population (2.44%,18/736) (P<0.01). The positivity rate of serum GBV-IgG antibody in blood donors was 1.02%-7.68%.</p><p><b>CONCLUSIONS</b>The positivity rates of serum GBV-IgG antibody among ethnic groups in the 3 provinces (region) had no significant differences; blood-borne transmission seemed to be an important transmission route of GBV, therefore supervision of blood donors and drug abusers should be intensified.</p>
